`Be it lrnown that I, NEWTON JAY Brenner, a citizen of the United States, .residing at Selma, inthe county of Dallas and `State of Alabama, have invented certain `nevv and useful Improvements in Shock Absorbers, of which the following is a specification, referencebeing had-to the accompanying drawings. A

This invention relates vto certain improvements in shock absorbers and it is anyobject yorf lthe yinvention to Aprovide ainovel and improved device of this general character constructed and 'operating in a manner to eliminate `any side sway and of rear and `front sway of the vehicle body.`

Anotherobjectnof :the invention iis ftoprovide a novelland improved device of `this general character Whiclrcoaots Ydirectly with the. spring of the vehicle together with an adjacent axle 'or housing and yoperates Iin a manner to prevent breakage of the spring when subjected vto undue stress or strain.V

An. additional object `o'l the invention is to provide anovel and improved device of this `general character which will not 'have a tendency Ato throw the rear axle `out Vof proper alignment and thereby tend to *break thefmotor supports, one that `Will perform quiclrlyand also act as asnubber. i

`It isalsolan object `of `the inventionto vprovidea `device oi' this general character emlbodying novel and improved means for securing `or` attaching the same to the axle, said iconnection or attachment also serving to provide an eiiicient means of fastening the radius rod to the axle.

The invention `consists `in the details 'ot construction and `in wthe combination and arrangement of the several parts ofiny im.- provedshock absorber whereby Certain iinportant advantages are attained and the de vice rendered simpler, less `expens ive `and `.Otherwise `more `convenient and advantage.n `ons for use, as will be hereinaftermore fully setforth.

The novel features of my invention will hereinafter be definitely claimed.

` In order that my invention maybe thebetter funderstood, I will 4novv `proceed vto de- Application filed Jully 10, 1924. 1Serial N vo. 725,245.

scribe the same with reference to the accentv panying drawings, Whereim.-

Figure 1 isa fragmentary view in elevan tionwith a `parit vin `section illustrating a shockabsorber `constructed in accordance with an embodiment of my invention and applied to the front alelota motor vehicle;

Figure 2 isa detailed sectional view taken substantially on the line 2 2 of Figure l;

Figure 3 is a View in top plan Aof the rocker'arm support as herein embodied and unapplied; Y

Figure 4 is an enlarged view in top plan of the roc-lier arm as herein disclosed imapplied; Y Figure 5 is a vien7 in elevation with a pore tion broken away illustrating an embodiment of my `invention for `use `in `connection `with a rear spring of a motor vehicle;

Figure `6, is a view in top plan of the rocker `arm as `disclosed in Figure 5 unapplied.

As disclosed n the accompanying drawings, A denotes the front axle'of a motor driven vehicle and S the semi-elliptic spring of a Well-,known type V.positioned above the axle and which isoperatively connected with the body of the vehicle (not shown) in any conventional manner.

Resting upon theaxle A in `desired position is a support l for the rocker arm R, said support being disposed lengthwise of the a Xle Aand having its inner end portion provide-,d with an upstanding lug 2 with which the arm JR is :directly engaged. The inner end eport-ion `ofthe support l is also provided ivith theoppositely disposed andlaterally directed stop lugs 3 operating to limit the :extent of swinging movement of the rocker arm, R in one direction. The outer extremity ofeach Aof the lugs 3 is provided with a'depending flange @i andthereby pro viding means :tor maintaining the support l in. applied position.

i The `opposite or outer end port-ion of' the support I is provided with an opening 5 through which `is adapted to be disposed from "below the anchoring bolt V6, said bolt being :also disposed frombeloiv through the axle A. The lower end portion of the bolt 6 has a tapered head i?. Goa'oting with the upper portion of the bolt and the upper surface of the support 1 is the nut S.

As particularly illustrated in Figure 1 of the accompanying drawings, this bolt 6 is also disposed upwardly through the outer end of the radius rod 9 and the head 7 of the bolt engaging therewith in a manner to effectively maintain said end portion of thc rod 9 in lirm connection with the axle A. By having the nut 8 at the top it is possible to tighten lthe rod 9 against the axle A by drawing the head 'l up against the radius rod without turning the head 7 and also theI vibrations due to the vehicle when in transit will not loosen the radius rod connection with the resultant rattling as all of the strain will be upon the head 7 and the liability substantially eliminated of the nut 9 being` stripped from the bolt 6.

The rocker arm 1t is substantially L1 shaped in form with its foot portion comprising a pair of spaced wings 10. The lug 2 extends upwardly between the inner portions of said wings 10 and is pivotally engaged therewith by the bolt 11 or the like whereby the arm it is supported for swinging movement in a vertical direction. The eye 12 carried by the adjacent end of the spring S is disposed between the outer ends of the wings 10 and through which is disposed the bolt 14 also extending through and supported by the wings 10. Vl"he stem portion of the rocker arm R comprises a pair of transversely spaced arms 15 the outer or free end portions of which being substantiallj,7 in parallelismand arranged at opposite sides of the spring S. 1

Straddling the spring S from below and predetermined point inwardly of the eye 12 is a saddle 16 held in applied position through the medium of the bolt 17. The saddle 16 at opposite sides is provided with outstanding plates 18 overlying the outer end portions of the arms 15 of the rocker arm R and interposed between each of said plates 18 and the outer end of an arm 15 is a coil spring 19 of requisite tension.

rilhe embodiment of my invention as illusrated in Figures 5 and-6 is substantially the same as hereinbefore described except that the rocker arm support 1a is directly 'associated with a rear axle housing and is disposed longitudinally on such curvature as to have requisite close contact therewith, the outer end portion of said support 1a being anchored or secured in applied position by the bolt 20.

Then the spring S compresses the arms 15 of the rocker arm R exert an upward Ythrust against the underside of the spring S through the coil springs 19, thus supporting the spring S and relieving the same of a `large portion of the strain imposed thereupon and thereby minimize the liability of said spring breakin.

The lugs 3 prevent the rocker arm or more particularly the arms 15 being swung too far downwardly and when said arms 15 come into contact with the lugs 3, the springs 19 then take up the shock and exert an upward force against the underside of the spring S. The location of the saddle 16 is such that the liability of breakage of the spring S is substantially eliminated.

rlhe springs 19 operate to relieve the adjacent outer end of the spring S of leverage action and when the spring S rebounds sufficiently it comes back to a shorter length and again forces the arms 15 into contact with the stop lugs 8. At this time the device begins to act as a snubber in that the spring S cannot shorten any further and the axle A and associated wheels must be picked up if the rebound of the car is sufficient. -For this reason the car or vehicler is prevented from turning or swinging sideways as the device at one side will work as a snubber while the device at the other side will work as a shock absorber.

As is believed to be obvious from the foregoing description and the disclosure in the accompanying drawings, the spring S cannot stretch out without working my improved device nor can weight or a quick spring at an end of the spring S be applied without the adjacent device functioning.

The end of the spring S goes down when weight is applied or when ythe axle A is forced up causing the rocker arm R to compress the coil springs 19 while at the same time the spring S at the point where the saddle 16 is positioned comes down and further compresses the springs 19. This double action is much quicker than a single action and therefore catches the shock' before bounce can happen. It also releases as quickly and thereby prevents a strong rebound. A

In claiming my invention reference there` in to an axleis to be understood as being the equivalent of a housing or other element with which the device may be employed` From the foregoing description it is thought to be obvious that a shock absorber constructed in accordance with my invention is particularly well adapted'for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself Vto the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

l claim In a shock absorber, in combination with an axle and a spring,a substantially L- sliapedlooker arm, a support mounted upon the axle, means for holding tlie support in applied position7 means for pivotally conneeting the foot portion of said rocker arm to the support, means for connecting the eX- tremity of the sp1-ing to the foot portion of the rocker arm, an expansible medium interposed between the stem portion of the rocker arm and the spring, and an outstanding lug carried by the axle for limiting the swinging movement of the stem poition of the rocker arm in a direction toward the axle.

In testimony whereof I hereunto afix my signature.
